Fitting for joining scaffold boards

Abstract

A fitting for transverse joining of two L-shaped sections is provided, each L-shaped section with a web part and a foot part. The sections are disposed with the web part back-to-back, being peculiar in that the fitting substantially includes a first flange and a second flange which are J-shaped and which in mutual contact are slidingly connected with a connection for constituting a largely C-shaped fitting with a gap of variable length for accommodating the two foot parts of the L-shaped sections. The fitting includes means for mutual fixation of the two flanges for retaining the length of the C-shaped fitting after receiving both foot parts in the C-shaped fitting.

1. Fitting for transverse joining of two L-shaped sections each with a web part and a foot part, separably connected to each other by said fitting with the web parts abutting back-to-back, comprising a first flange and a second flange which are J-shaped with straight back sections and bent parts, wherein the straight back section of one of the flanges is substantially parallel to the tip of the bent part of that flange, and which in mutual contact along an exterior surface of their straight back sections are slidingly connected with a connection for constituting a largely C-shaped fitting with a gap of variable length for accommodating the two foot parts of the L-shaped sections, and wherein the first flange has a first hollow for part for accommodation of one foot part without clamping action, and wherein a hollow of the second flange has a width which is less than the sum of the material thickness of the first flange at a length extending into the hollow of the second flange and the width of the first hollow at its narrowest point in order thereby to allow accommodation of the other foot part under clamping action; wherein the first flange is further provided with a first bent lug on its straight back section and wherein the first bent lug is intended for bearing against the foot parts after inserting the foot parts in the first flange and wherein the first lug has a notch for accommodating the bent part of the second flange, and wherein the notch is dimensioned for contact with the outer edge of the bent part of the second flange with an inner edge of the notch in order to prevent deflection of the bent part of the second flange when accommodating the foot parts under clamping action. 
   
   
     2. Fitting according to  claim 1 , wherein the connection includes a screw for fastening in the back of the first flange, and wherein the screw extends through an aperture in the back of the second flange. 
   
   
     3. Fitting according to  claim 1 , wherein the first hollow is narrowing. 
   
   
     4. Fitting according to  claim 1 , wherein the second flange is provided with a second bent lug on its straight back section, and wherein the second bent lug is intended as a striking surface when dismounting the fitting. 
   
   
     5. Fitting according to  claim 4 , wherein the second bent lug is provided at the end of the straight back section of the second flange, such that the combination of the J-shaped second flange with the second bent lug is substantially G-shaped. 
   
   
     6. Fitting according to  claim 1 , wherein the first bent lug is provided at the end of the straight back section of the first flange, such that the combination of the J-shaped first flange with the first bent lug is substantially G-shaped. 
   
   
     7. Fitting assembly comprising a fitting transversely joining two L-shaped sections, wherein the two L-shaped sections each comprise a web part and a foot part, wherein the sections are separably connected to each other by said fitting with the web parts abutting back-to-back, wherein the fitting substantially includes a first flange and a second flange which are J-shaped with straight back sections and bent parts, wherein the straight back section of one of the flanges is substantially parallel to the tip of the bent part of that flange, and which in mutual contact are slidingly connected with a connection for constituting a largely C-shaped fitting with a gap of variable length for accommodating the two foot parts of the L-shaped sections, and wherein the fitting includes means for mutual fixation of the two flanges for retaining the length of the C-shaped fitting after receiving both foot parts in the C-shaped fitting, wherein the two L-shaped sections are a pair of downwardly extending side members at the long sides of two mutually abutting scaffold boards, each scaffold board having a substantially C-shaped cross-section formed by a board face and one said downwardly extending side member at both long sides of said board face; wherein the means for mutual fixation comprises the first flange being further provided with a first bent lug on its straight back section and wherein the first bent lug is intended for bearing against the foot parts after inserting the foot parts in the first flange and wherein the first lug has a notch for accommodating the bent part of the second flange, and wherein the notch is dimensioned for contact with the outer edge of the bent part of the second flange with an inner edge of the notch in order to prevent deflection of the bent part of the second flange when accommodating the foot parts under clamping action. 
   
   
     8. Fitting according  claim 7 , wherein the connection includes a screw for fastening in the back of the first flange, and wherein the screw extends through an aperture in the back of the second flange. 
   
   
     9. Fitting according to  claim 8  wherein said screw is permanently affixed to said first flange. 
   
   
     10. Fitting for transverse joining of two L-shaped sections each with a web part and a foot part, separably connected to each other by said fitting with the web parts abutting back-to-back, comprising a first flange and a second flange which are J-shaped and which in mutual contact are slidingly connected with a connection for constituting a largely C-shaped fitting with a gap of variable length for accommodating the two foot parts of the L-shaped sections, and wherein the first flange has a first hollow for accommodation of one foot part without clamping action, and wherein a hollow of the second flange has a width which is less than the sum of the material thickness of the first flange at the length extending into the hollow of the second flange and the width of the first hollow at its narrowest point in order thereby to allow accommodation of the other foot part under clamping action, wherein the connection includes a screw for fastening in the back of the first flange, and wherein the screw extends through an aperture in the back of the second flange, wherein said screw is permanently affixed to said first flange but does not fix the flanges in place with respect to one another; wherein the first flange is further provided with a first bent lug on its straight back section and wherein the first bent lug is intended for bearing against the foot parts after inserting the foot parts in the first flange and wherein the first lug has a notch for accommodating the bent part of the second flange, and wherein the notch is dimensioned for contact with the outer edge of the bent part of the second flange with an inner edge of the notch in order to prevent deflection of the bent part of the second flange when accommodating the foot parts under clamping action.
